In Week 5 we will continue to focus on using spreadsheets to analyze data and begin to use R.
However I think it may be hard, in some cases, to get a visual-spatial sense of what these census-tract numbers mean if you do not have an actual map of the census tracts for your county. So I have generated maps of each of the counties, sometimes at two different scales to show large and small tracts. I am posting them here for you to download. They are almost one megabyte each, which is no problem for a download but too big for an email attachment.
These files are all in Scalable Vector Graphics format. You can display/print these images in a web browser, most graphics programs, or a word document. You can also edit SVG graphics, most easily with Inkscape. I am assuming most of you will only use these as reference-maps to help you get a sense of where your tracts are located. So I am not requiring you to learn Inkscape, just letting you know that you have the option of editing these graphics in a free, open-source program similar to Adobe Illustrator.
